Abstract
A video processing method and apparatus for processing video frames comprising animated images so as to blur movement of the animated images between successive frames, the method or apparatus comparing a first input frame with the following input frame; identifying moving areas in the first input frame by the comparison; calculating the velocity of the movement of the moving areas between the first and following input frame; summing, only for each input pixel site within the identified moving areas of the input frame, the pixel value of each input pixel site and adjacent pixel values determined according to the calculated velocities and a predetermined aperture type for the input frame; and providing an output frame from at least the summed pixel values and pixel values of areas of the input frame other than the moving area, the adjacent pixel values either being the pixel values of pixel sites in the input frame which are spatially adjacent in the direction of the velocity or predicted temporally adjacent pixel values for each input pixel site for times intermediate the predetermined aperture time.
